I don't know if it's the transmitter's fault or if I'm doing something wrong. When transmitting in the car, the sound is very quiet, so I have to turn the volume way up in the car. But then there is a lot of interference too. I've tried different tuning frequencies without much difference in the sound quality or volume. I hope I can find a solution and give it five stars, because in terms of design and quality it seems decent.

It's okay for the money, I think. It falls short in the microphone, and it doesn't have a strong transmitter for the signal. In a city with many frequencies, it struggles a lot. Otherwise, good build quality.

Although it says it receives frequencies from 87.5 to 108, in reality it receives from 88.1 to 107.9. Oddly enough, it tunes to 107.9 with the radio at 108. I don't know how long it will stay like this or whether it will pick up any station in another city.

Good, very good, I would like to be able to use the charging cable as an AUX as well, but okay, we can't have everything at this price. Very fair overall, I highly recommend it at the 16 euros I bought it for

Very good music quality. Acceptable call quality. Stable Bluetooth. It takes a memory card to permanently store songs on the device if you want. It has a 3.5mm jack connection. It is perfect for 16€.

The Baseus S-13 is an excellent technical solution for upgrading the infotainment system of older vehicles. The stability of the FM signal is exemplary, showing minimal to zero interferences even in densely populated areas with a saturated radio spectrum. The sound performance during music playback is crystal clear, maintaining the dynamic range of frequencies without distortions.

In terms of hands-free functionality, the device operates reliably, although there is a slight deviation in the output level (gain) during calls, which requires manual volume increase from the radio's main unit for optimal acoustics. Despite this small 'offset' in call volume, its overall performance, build quality, and Bluetooth pairing speed rank it among the top FM transmitters on the market.

the only bad thing is that it doesn't go down to stations 87.5 - 88.9 if I remember correctly, I use it with Bluetooth and with usb I listen to music from it!

It was not working due to intermittent connectivity and disconnection on Toyota Raw4 jeep. I bought better model and its working. I wanted to turn it back and rejected will use my consumer law rights

especially in Athens you will NOT find an empty frequency, buying this is pointless, not because of the product but because of the essence of the matter.

Good for its money but it has some issues!
1) When I connect the mobile phone, the music does not play from the USB, which means I can only use one function with good results
2) If I have many folders on the USB, I cannot choose whichever I want because the screen gives no information about the contents
3) The sound quality is inferior to the car radio (Panasonic) and there is quite a bit of distortion at high volume.
4) It is a bit difficult to handle when the cigarette lighter power supply is a bit far from the dashboard (this is not the device's fault)

While during the first 3 months of use it was excellent, after a certain point it caused an electrical problem in my car; when I plugged it in, the hazard lights would flash for no reason until I removed it. I stopped using it so it wouldn't cause me more problems

I bought it with reservations but it eventually exceeded my expectations. It connected easily, the sound is very good. And I listen to my favorite songs (Spotify, YouTube, SD, etc.) without any interference. You just need to find the right frequency. It is a very good solution for old cars. Also very good for calls. It made driving much easier for me.

Good as long as it is connected
The problem is
1) they can't hear you clearly on speakerphone
2) it disconnects often, e.g., when you talk and when the call ends you have to connect again to continue listening to music
That's all..

Very good quality, I tried it on a Chinese car radio I have at home, it played as if you have a real BT, but it didn't fit in my car and I got annoyed (Toyota Yaris XP10 phase 2)

It does exactly what it promises without disconnecting. An extra cable from 3.5mm to 3.5mm is also included for cars that accept and have an auxiliary output for perfect sound. Even if your smartphone does not accept it, there is a small cable available on the market from mini USB to jack, at a very low cost (for residents of urban centers who complain that they cannot easily find a frequency without interference). 5 stars from me then.

It syncs very easily and instantly via bluetooth with the phone. The sound is very loud and clear. It plays music from the phone easily and clearly. It is effective for answering calls. I find it a bit difficult to play music from an sd memory card but maybe it just needs some getting used to. Sometimes when we make calls, the sound is not heard. I haven't checked if the problem is caused by a smartwatch. I recommend it.

very good solution to connect the phone with the car speakers, sleek, you can stick the screen to the dashboard, easy to use with clear instructions

I was also looking for a quick solution to listen to songs from my phone. It's very good for the money, although sometimes it has some glitches. We'll see how long it lasts. For now, I am satisfied!

It connects immediately to the phone. It works very well without interference. I play from the phone Spotify, Youtube, Eradio, and whatever else I want in the car. Also, you can charge 2 phones at the same time. I have bought 2 and I am very satisfied. It is definitely worth the money.

It caused an issue with the central locking of the car, I don't exactly understand how, but as soon as I removed it the problem was fixed. So it causes interference. It works well but you won't be thrilled by the sound either.

Very good device, very high quality for its cost and particularly easy to handle with flawless performance on Bluetooth, however for Athens unfortunately there is no free frequency so it makes it practically useless. When you go outside, its operation is a pleasure.

For the money, it's very good. I have had it for 3 years and it works perfectly. It is easy to use and very convenient due to the different connectivity options it offers. The only complaint is that sometimes when nothing is playing through it on the radio, it makes some static, but otherwise, if you play music, it doesn't make any noise at all.

Use as a car charger only, it works like a charm, provides quick charge and really saves you... be careful with the cable that will be used.

Very good for its price, it was worth the extra something compared to other products of its kind. On busy avenues, it has a few interruptions but they can be resolved by changing the frequency. This, of course, varies from area to area. Every time I have been in downtown Athens, I did not encounter any particular issue. As for calls, the quality of the microphone is okay, you just need to speak clearly and a little louder than usual.

It has the advantage that it plays a stick for music and has a slot for a small memory card. It is not particularly durable and reliable. I have had it for less than a year and it no longer works. Its use was light and not very frequent. Interference from other frequencies occurred relatively easily. My opinion is STAY AWAY!

I have had it for about a year and I am very satisfied! I have removed the car antenna so that it does not snow

Functional product, good build quality, aesthetically pleasing, convenient size! It's the second day I'm using it and I'm very satisfied. If you find the right empty frequency depending on where you are, of course..... then it doesn't create any interference in the sound! It's been amazing so far!

It has been 1 month since I bought it, for the money it's okay; I would say. I don't use it much because sometimes it loses signal, stops playing music, skips songs... I don't know if it's the car radio or this.

Amazing. I have been using it for music for 1 year and it has never disconnected or caused any difficulties in connection. Very convenient for calls as well.

Very decent product. It does what it says. You can listen to music and answer calls if needed.
